Steam Boilers and Steam Systems: Operation, Water Treatment and Troubleshooting – Dubai, 8–12 Mar 2027

Programme overview

Introduction:

Steam boilers fail in predictable ways: drum level swings trip the unit, poor water chemistry leaves scale and corrosion on tubes, carryover fouls downstream users, failed steam traps waste fuel and safety valves go untested. Each event costs production and raises the risk of a pressure-part failure. This Core Concept course trains boiler house staff and utilities engineers to run fire-tube, water-tube and waste heat boilers within safe limits, control feedwater and blowdown, survey the steam and condensate network and diagnose recurring faults. Participants complete a Boiler House Operating Log and Steam System Survey Pack.

Course Objectives:

• Distinguish fire-tube, water-tube and heat recovery steam generator designs and explain how drum, downcomer, riser, superheater and economiser circuits behave in service
• Operate boiler start-up, warm-up, load change and shutdown sequences, including purge, light-off permissives and low-water cutoff checks
• Control drum level, feedwater flow, deaerator operation and continuous and bottom blowdown to hold water chemistry within target limits
• Survey steam mains, pressure reducing stations, steam traps and condensate return lines and record losses on a site survey sheet
• Estimate boiler efficiency by the direct and indirect methods and rank flue gas, blowdown, radiation and trap losses
• Diagnose tube leaks, scaling, carryover, priming and water hammer from operating symptoms and inspection findings

Target Audience:

• Operators who run boilers, feedwater pumps and deaerators on shift in utilities and boiler houses
• Shift supervisors who authorise boiler start-ups, respond to alarms and trips and sign off operating logs
• Utilities engineers who set steam system operating limits and monitor boiler performance and fuel use
• Water treatment staff who sample feedwater and boiler water and adjust chemical dosing and blowdown
• Maintenance and inspection staff who service burners, valves and traps and prepare boilers for statutory inspection

Skills You Will Gain:

• Steam Table Interpretation
• Drum Level Control
• Burner Interlock Verification
• Boiler Water Chemistry Control
• Blowdown Management
• Steam Trap Testing
• Boiler Heat Loss Analysis
• Boiler Failure Diagnosis

Why Attend This Course:

• Return with a Boiler House Operating Log and Steam System Survey Pack prepared for boilers and steam lines on your own site
• Cut fuel and water use by finding failed traps, excess blowdown and uninsulated steam lines during routine rounds
• Handle start-ups, alarms and trips with a clear understanding of what each interlock and safety device is protecting
• Compare boiler house practice with operators and engineers from process industries, utilities, food production and healthcare facilities

Conclusion:

Safe, efficient steam boilers depend on sound control of level, combustion and water chemistry and on a steam network that returns its condensate. The course moves from boiler types and steam generation principles, through the construction code, control loops and protective devices, to start-up, deaeration, sampling, blowdown and steam distribution, then trap testing, efficiency losses and tube failure diagnosis. The final day applies these checks in walkthroughs and case reviews and produces a Boiler House Operating Log and Steam System Survey Pack.
